ADO Command and Stored Procedures

Introduction

You can design stored procedures to hide such complexities, leaving a more concise interface available for application development.

The command object has the power to change the query each time it is used. The code below demonstrates how to use the ADO command object with these stored procedure. First, create the command object and connect the connection object to the command object.

'create a command object
set cm = Server.CreateObject("ADODB.Command")
'connect the command
cm.ActiveConnection = cn

Next, specify the query.

Method 1

set cm.CommandText = "Select * from schools"

Method 2 (Table)

set cm.CommandText = "schools"
cm.CommandType = adCmdTable


Method 3 (Stored Procedure)

set cm.CommandText = "add_school"
cmdCommandType = adCmdStoredProc

Method 4 (Stored Procedure with Parameters)

set cm.CommandText = "add_school"
cm.cmdCommandType = adCmdStoredProc

set p = cm.Parameters

p.Append cm.CreateParameter("@style",adChar,adParamInput,50)
p.Append cm.CreateParameter("@school", adChar, adParamInput,50)
p.Append cm.CreateParameter("@id",adInteger,adParamInput)

cm("@style") = "Kempo"
cm("@school") = "WSU"
cm(Id) = 1

cm.execute

Method 5 ( Return the results to a recordset)

rs.Open cm, cn

Method 6 ( Recordset, type, and locking method)

rs.Open cm, cn, adOpenKeyset, adLockOptimistic

    How do you easy add or update a recordset when you have opened it using a stored procedure?


    I'm making a program where the user sees a recordset as a grid (used SP).  The user can edit rows or add new ones by going into detail mode.  (I use a tabstrip where Grid is on the first and a detail frame is on the second tab.)  When user goes into editmode I want the user to manipulate the record and be able to update or add.


    But it seems that SP only return readonly recordsets.  Is that so?


    How do one then implement the grid/detail scenario when using stored procedures?


    Examples are preferred!!
